If you keep some cash in your brokerage account, it's a nice perk when that cash is earning a high interest rate. Interest on uninvested cash within a brokerage account is often referred to as a "cash sweep," which is just what it sounds like — some brokers sweep your cash into high-yield options. Other brokers offer a high-yield savings account or cash account with a high interest rate, but you can typically move money back and forth easily and for free.
Here are all the brokers that made our list of the best for interest on uninvested cash.
Broker | Interest rate |
|---|---|
0.01% for free accounts, 4% for Gold accounts as a cash sweep With its easy-to-use margin offerings, fractional share capabilities and wide investment selection, it's no wonder Robinhood has become a household name among stock trading apps. Robinhood Gold costs $5 per month ($60 per year). | |
3.65% as a cash sweep Vanguard is known for low-cost investing, making it ideal for buy-and-hold investors and retirement savers. Active traders may find the broker lacking despite its $0 stock trading commission, due to its low-level trading platform and small selection of research and data. | |
0.50% - 4.10% in cash accounts Webull offers a slick interface and delivers an impressive array of tools for active traders and a wide investment selection, including stocks (plus fractional shares), options, ETFs, crypto, commodities and futures. However, it lacks access to mutual funds. Webull Premium clients ($3.99 per month or $40 per year when paid annually) earn 4.1%. Non-subscribers earn 3.75% with account balances over $25,000 and 0.50% on account values below that. | |
4.10% in a high-yield cash account Public provides free stock and ETF trades, pays you to trade options, and gives traders access to crypto and bonds. The platform will appeal to traders looking for a low-cost options broker and access to many types of assets. | |
4.10% as a cash sweep Moomoo offers free stock and option trades in an easy-to-use trading platform that charges low margin rates. It's not built for passive retirement investors — IRAs aren't supported, nor are mutual funds — but there's a lot to like about Moomoo for more active traders. | |
4% in a high-yield savings account M1 Finance stands out for its unique investment approach — it helps investors visualize their portfolios as a pie, with "slices" made up of different securities. The mix of automation and manual investing will appeal to beginner investors who want to grow their skills and long-term investors who want help maintaining their portfolio allocation. | |
3.92% as a cash sweep Fidelity is one of the largest and most well-established brokerages, and it shows. Fidelity charges no trading commissions and offers an extensive set of no-fee, no-minimum index funds. It also stands out for its top-notch research tools, a renowned trading platform and very strong customer service. | |

Brokerage accounts vs. bank accounts for earning interest
While these brokers pay interest similar to what you'd receive in a savings account, there are a number of differences to be aware of, including deposit insurance and features.
Deposit insurance
Savings accounts are insured by the Federal Deposit Insurance Corp. (FDIC), which protects up to $250,000 per person, per bank.
All of the brokerages above are members of the Securities Investor Protection Corp. (SIPC), which protects up to $500,000 per person (up to $250,000 in cash), per brokerage account in the event that the broker becomes insolvent.
However, SIPC coverage doesn't protect the value of money market funds, such as those that Vanguard sweep funds into by default. In other words, SIPC coverage doesn't necessarily cover the exact dollar amount of cash in a brokerage account the way FDIC coverage does in a savings account.
Is a brokerage account a good place to earn interest?
Bill Hampton, a financial consultant based in Atlanta, says that brokerage accounts can be good places to earn interest — for savers who don’t need immediate access to their money.
However, Hampton says that some brokerage accounts have limitations. “For instance, some do not offer the ability to write checks like a bank would. Some limit the amount of transactions you can make in a particular month,” Hampton says.
“A client would have to determine if it’s a long-term savings account that they’re not going to touch for six months or a year, or if it’s going to be an emergency fund that they don’t plan to utilize. If it’s going to be their regular account that they move cash in and out of, they may want to check with the restrictions that each brokerage firm has,” Hampton says.
He points out that many accounts are limited to six transactions per month, which is “plenty in most cases.”
Hampton says that despite these limitations, brokerage accounts can still be a viable option for savers who are seeking high yields and don’t need to touch their money several times a week.
“If individuals or clients can find better rates at a brokerage firm than at their local bank, which is most likely, then that’s a very good opportunity to earn a high interest rate,” he says.

Methodology
NerdWallet’s comprehensive review process evaluates and ranks the largest U.S. brokerage firms by assets under management, along with emerging industry players. Our aim is to provide an independent assessment of providers to help arm you with information to make sound, informed judgements on which ones will best meet your needs. We adhere to strict guidelines for editorial integrity.
We collect data directly from providers through detailed questionnaires, and conduct first-hand testing and observation through provider demonstrations. The questionnaire answers, combined with demonstrations, interviews of personnel at the providers and our specialists’ hands-on research, fuel our proprietary assessment process that scores each provider’s performance across more than 20 factors. The final output produces star ratings from poor (one star) to excellent (five stars).
